Try and cover the most of the electrics, and use de-greaser

Get the engine up to temp.. Leave it running at all times. Cover the coil/dizzy and alarm. Spray traffic film remover (TFR) all over the engine bay and engine let stand for a min then power wash everywere. Leave the engine running for anothe 20mins or so when done to dry off. It will come up like brand new mate. Also if you want the black bits like the air box and wiring plastic to look new just spray abit of duck oil over them afterwards.

As long as you cover the air filter there's not really any need to have the engine running. Whenever I've done it I've just switched the engine off, covered the air filter and any electrical components with poly bags, slapped on some degreaser left it for 10 minutes then rinsed it. If you leave your engine running and spray the exhaust manifold there's a chance it could crack... albeit a small chance but I wouldn't fancy it.

I'm not saying you should have the engine off, just that if you do it right it's fine either way.

i tried this and the degreaser just baked on and dried out because most of the comonents were too warm. i reckon it's best done on a cold engine

I use a garden hose, purely for the fact that I'm a bit paranoid about knocking shit about - the only pressure washers I have access to are high pressured. Plus, by the time the de-greaser's worked there's not really any need for any sort of pressurised rinser.

Jet wash it with the engine on. Spray wheel cleaner on it all and agitate. Jet wash off

Haven't done mine yet but when I do it won't be with a running engine or a pressure washer.. Degresser, hose and elbow grease is the best bet..

wheel cleaner will make your plastic parts go white, dont use that, NEVER! use a jet wash under the bonnet!! you dont want water in electric parts, even when you cover parts up water finds its way anywhere, brake cleaner (degreaser) works wonders degrease the bay then use polish and wax

Just dont pepper the exhaust.. Ive done mine this way for years. And even won show and shine trophy's on an everyday driver
Never ever wash it with the engine cold or not running.. Bad move.. If you pepper the alty or dizzy or round the back on the starter.. it may not start again. engine running dry's this out. This is way valeters do it anyways. This is what i was told by a good one. So ive done it for years

Whenever I have done it, I sprayed with TFR or similar, Left for a few minutes, Started the car then used a preassure washer on it. Just don't point it directly at the electrics or air filter.

wheel cleaner that the cleaners use at our work is wheel acid, it bleeches plastic and makes it go white like bird shit

I've pressure washed many an engine and they're all still going.

Unless it's an old nova or something you'd need to be trying to damage anything.

As said TFR if you can get some is your best bet, cover wings in black bags, spray on leave for 5 minutes aggitate with brushes in hard to get to places then jet wash off. Start the car after and allow to dry. The amount of engines I have cleaned and never covered anything up and always used a jet wash I can honestly say I have never ever had a problem. Engines can get wet these days.

cleaned mine yesterday, used auto glym engine and machine cleaner and a brush to agitate everywhere then pressure washed off and started car to let it dry, then covered all plastics in auto glym vinyle and rubber care, looks very good now.
